Embodiment
Below in conjunction with accompanying drawing, shown in Fig. 1 ~ Fig. 7, invention is described in further detail.
Fig. 1 is exploitation device filling-valve of the present invention original state structural representation in one embodiment.Fill one end of valve body 10, offer spool bore 11 vertically, coaxially offer in the bottom of spool bore 11 and fill chamber 12, the filling of filling hole 13(and filling liquid carbon dioxide is input into gas port) offer along filling the axis of valve body 10, with spool bore 11 and fill chamber 12 and be communicated with.It is interior threaded hole (top and the bottom are all without screw thread) at the middle part of spool bore 11.Spool 20 cylindrical offers the outside thread corresponding to this interior threaded hole, and therefore, spool 20 can be formed with spool bore 11 and be threaded, and is connected in spool bore 11, and can moving axially along spool bore 11.When spool 20 is threaded with spool bore 11, when being positioned at position shown in Fig. 1, the sealed end 21 of spool 20 is arranged in the 11a region, bottom of spool bore 11, and filling hole 13 is communicated with filling chamber 12, and namely sealed end 21 does not form sealing to the air inlet of filling chamber 12.When spool 20 is threaded with spool bore 11, when being positioned at position shown in Fig. 2, the sealed end 21 of spool 20 is formed with the suction port 12a filling chamber 12 and seals, and has blocked filling hole 13 and has been communicated with filling chamber 12.It should be noted that, above-mentioned filling valve body 10 can be set up separately, and the receiving cavity exploiting device in use with carbon dioxide is communicated with, simultaneously, also can exploit being processed as one of device structure with carbon dioxide, make the structure of carbon dioxide exploitation device more compact simultaneously, use more convenient.
The present invention exploits the working procedure of device filling-valve.By the spool 20 of exploitation device filling-valve, rotate to position shown in Fig. 1, be connected by filling hole 13 with liquid carbon dioxide supplier, because filling hole 13 is communicated with filling chamber 12, therefore liquid carbon dioxide is injected into and fills in chamber 12.Fill chamber 12 to be communicated with the receiving cavity that carbon dioxide exploits device, thus the liquid carbon dioxide achieving carbon dioxide exploitation device is filled.After filling is full, to filling valve body 10 internal rotating spool 20, rotate to position shown in Fig. 2, the sealed end 21 of spool 20 is formed with the suction port 12a filling chamber 12 and seals, and closing liquid appliance for applying carbon dioxide, the operation of filling liquid carbon dioxide completes.In blasting process, liquid carbon dioxide detonation in carbon dioxide exploitation device, the sealed end 21 of spool 20, all the time keep sealing with the suction port 12a filling chamber 12, therefore, the present invention exploits device filling-valve and can exploit in device by effective guarantee carbon dioxide, the normal use of liquid carbon dioxide.
Exploiting device filling-valve for making the present invention can be operated in the environment of high pressure, high temperature, strengthens filling the sealing effect between chamber 12 and filling hole 13, therefore, on the one hand, fills chamber 12 suction port 12a and can adopt annular boss forms.On the other hand, also can improve the structure of the sealed end 21 of spool 20, therefore, as shown in Figure 3, in one embodiment of the invention, to the end face of spool 20 sealed end 21, coaxially offer closed hole 21a, in closed hole 21a, assemble soft metal material sealing gasket 21b, the diameter of sealing gasket 21b is corresponding to the internal diameter of closed hole 21a, height can be greater than the closed hole 21a degree of depth (schematic structure), also can be equal to or slightly less than the closed hole 21a degree of depth.Soft metal material can be preferred, and Vickers hardness number is at the Cuprum alloy of 55 ~ 85HV or aluminum alloy material.Therefore, as the sealing gasket 21b in sealed end 21 and between annular protrusion suction port 12a, when producing certain applying power, sealing gasket 21b, by generation distortion (producing ring-type impression on sealing gasket 21b), and forms cambered surface and seals between suction port 12a.Therefore better sealing effect is obtained.
Meanwhile, as shown in Figure 4, in another embodiment of the invention, another kind of seal form of filling between chamber 12 and filling hole 13 is additionally provided.On the sealed end 21 of spool 20, offer concentric seal groove 21c, 21d, and at this concentric seal groove 21c, corresponding " O " RunddichtringO is equipped with in 21d, its concentric seal groove 21c, the position of 21d is corresponding to the position of annular protrusion, concentric seal groove 21c, spacing between 21d is corresponding to the width of annular protrusion (filling the annular protrusion at the suction port 12a place in chamber 12), its width will ensure, when the sealed end 21 of spool 20 is formed closed with the suction port 12a filling chamber 12, make concentric seal ring 21c, 21d, be squeezed in the both sides (as content represented by dotted line in figure) of annular protrusion respectively.It should be noted that, for ensureing sealing effect, above-mentioned seal ring can also adopt soft metal alloy material, or can be one-body molded with concentric seal groove 21c, 21d.Thus both sides form multidimensional seal inside and outside suction port 12a, thus further increase sealing effect.It is pointed out that the sealed end 21 of spool 20 also can adopt taper, it is advantageous that at some under the less demanding occasion of sealing effect, sealing surface can be determined according to the actual processing of suction port 12a, and the enforcement of structure is more flexible simultaneously.
Considering that liquid carbon dioxide is liquid state compounding substances, therefore for making liquid carbon dioxide in the filling process, not easily revealing from filling the threaded connection place of valve body 10 with spool 20.As shown in Figure 5, in one embodiment of the invention, be also fixed with seal ring 23 at the screw terminal 22 of spool 20, sealing ring 23 can with spool 20 one machine shaping (schematic structure), simultaneously also can process laggard luggage respectively and join.The aperture of spool bore 11 top 11b and seal ring 23 external diameter corresponding, be preferably transition fit relation.The cylindrical of seal ring 23 also offers seal groove 23a, in seal groove 23a, assembles its corresponding " O " RunddichtringO 24.Thus in liquid carbon dioxide injection process, between filling valve body 10, form leak-tight closure at spool 20, and do not affect the linear relative movement of spool 20 in valve body 10, therefore, obtain better sealing effect.
For preventing carbon dioxide collector after blast, inside still has residual carbon dioxide not discharge.Therefore, as described in Figure 6, in one embodiment of the invention, the sealed end 21 of spool 20 offers elastic packing hole 25, and at the bottom assembling spring 26 in this elastic packing hole 25, the other end of spring 26 is fixedly connected with sealing camel 27.The external diameter of its spring 26 and sealing camel 27 is corresponding to the aperture in elastic packing hole 25.Therefore, after the blast of carbon dioxide collector completes, rotate up spool 20, spring 26 gradually reduces the applying power to the suction port 12a filling chamber 12, if now still have gas residue in filling chamber 12, and possesses certain pressure, spring 26 can with its gradually with its balance (compressive force of spring 26 is set as safety relief power), and can not outwards release place is larger suddenly pressure, thus be more conducive to the safety operation of personnel, improve the usability of device.
For making spool 20 more stable when sealing, be not vulnerable to the impact be threaded between filling-valve body 10 with spool 20, therefore, as described in Figure 7, in one embodiment of the invention, also be fixed with stop nut 30 at the screw terminal 22 of spool 20, thus screw terminal 22 is fixedly connected with filling valve body 10.Therefore, in carbon dioxide collector blast process, the sealing between spool 20 and the suction port 12a filling chamber 12 can not be made due to vibrations to produce and to loosen, improve the stability of device entirety.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
